What is the fate of pyruvate during anaerobic respiration in yeast cells?
Answer and explanation
Correct answer: D. It is converted into ethanol, carbon dioxide, and energy
- Step 1: In yeast during anaerobic fermentation, pyruvate is decarboxylated and reduced: .
- Step 2: Lactic acid fermentation occurs in human skeletal muscle cells during vigorous exercise under oxygen deficit.
Answer
It is converted into ethanol, carbon dioxide, and energy.
Why not the others: Lactic acid is produced in mammalian muscle tissues; complete breakdown to water and occurs in aerobic mitochondrial respiration.
